# NAME
Sque - Background job processing based on Resque, using Stomp
# VERSION
version 0.004
# SYNOPSIS
First you create a Sque instance where you configure the [Stomp](http://search.cpan.org/perldoc?Stomp)
backend and then you can start sending jobs to be done by workers:
use Sque;
my $s = Sque->new( stomp => '127.0.0.1:61613' );
$s->push( my_queue => {
class => 'My::Task',
args => [ 'Hello world!' ]
});
You can also send by just using:
$s->push({
class => 'My::Task',
args => [ 'Hello world!' ]
});
In this case, the queue will be set automatically automatically to the
job class name with colons replaced with hyphens, which in this
case would be 'My-Task'.
Additionally, the [sque](http://search.cpan.org/perldoc?sque) command-line tool can be used to send messages:
$ sque send -h 127.0.0.1 -p 61613 -c My::Task 'Hello world!'
Background jobs can be any perl module that implement a perform() function.
The [Sque::Job](http://search.cpan.org/perldoc?Sque::Job) object is passed as the only argument to this function:
package My::Task;
use strict;
use 5.10.0;
sub perform {
my ( $job ) = @_;
say $job->args->[0];
}
1;
Background jobs can also be OO. The perform function will still be called
with the [Sque::Job](http://search.cpan.org/perldoc?Sque::Job) object as the only argument:
package My::Task;
use strict;
use 5.10.0;
use Moose;
with 'Role::Awesome';
has attr => ( is => 'ro', default => 'Where am I?' );
sub perform {
my ( $self, $job ) = @_;
say $self->attr;
say $job->args->[0];
}
1;
Finally, you run your jobs by instancing a [Sque::Worker](http://search.cpan.org/perldoc?Sque::Worker) and telling it
to listen to one or more queues:
use Sque;
my $w = Sque->new( stomp => '127.0.0.1:61613' )->worker;
$w->add_queues('my_queue');
$w->work;
Or you can simply use the [sque](http://search.cpan.org/perldoc?sque) command-line tool which uses [App::Sque](http://search.cpan.org/perldoc?App::Sque)
like so:
$ sque work --host 127.0.0.1 --port 61613 --workers 5 --lib ./lib --lib ./lib2 --queues Queue1,Queue2,Queue3
# DESCRIPTION
This is a copy of [resque-perl](https://github.com/diegok/resque-perl)
by [Diego Kuperman](https://github.com/diegok) simplified a little bit
(for better or worse) and made to work with any stomp server rather than Redis.
# ATTRIBUTES
## stomp
A Stomp Client on this sque instance.
## namespace
Namespace for queues, default is 'sque'
## worker
A [Sque::Worker](http://search.cpan.org/perldoc?Sque::Worker) on this sque instance.
# METHODS
## push
Pushes a job onto a queue. Queue name should be a string and the
item should be a [Sque::Job](http://search.cpan.org/perldoc?Sque::Job) object or a hashref containing:
class - The String name of the job class to run.
args - Any arrayref of arguments to pass the job.
Example:
$sque->push( archive => { class => 'Archive', args => [ 35, 'tar' ] } )
## pop
Pops a job off a queue. Queue name should be a string.
Returns a l object.
## key
Concatenate `$self-`namespace> with the received array of names
to build a redis key name for this sque instance.
## new_job
Build a [Sque::Job](http://search.cpan.org/perldoc?Sque::Job) object on this system for the given
hashref(see [Sque::Job](http://search.cpan.org/perldoc?Sque::Job)) or string(payload for object).
# ATTRIBUTES
# HELPER METHODS
# TODO
- Make App::Sque that will let you run sque and just pass it the
stomp server/port, queue list, lib directories (if needed), and
number of workers.
- More (real) tests.
